When it comes to auctioning off world-renowned pieces of art and antiquities to wealthy buyers, Sotheby’s has it covered, with items frequently fetching millions of dollars and breaking records. But how much are people willing to pay for rare, one-of-a-kind experiences that involve, say, celebrities or Michelin-starred private tasting menus? Well, we're about to find out as the auction house is partnering with experiential marketplace IfOnly.com to host its first ever online bidding war of once-in-a-lifetime events.

The “IfOnly Presents: Experiences Auction” will run from Cyber Monday (November 28) through December 9 and feature items like lunch with celebrity stylist Rachel Zoe ($10,000), an opportunity to attend the LondonStar Wars premiere and after party with Forest Whitaker ($50,000), and tickets to the NBA All-Stars Weekend in New Orleans with Milwaukee Bucks Owner Marc Lasry ($50,000).

The extravagant list doesn't end there, however. In addition to celebrity experiences, Sotheby's will also be auctioning off over 25 exclusive packages that include adventure, culinary, and athletic experiences, with a portion of the selling price of every item going to charities around the world. Always dreamed to traveling to Bali? Bid on a 10-day trip with a National Geographic photographer ($12,500 per person). More of a tennis fan? There's a private lesson with former pro and Olympian Brad Gilbert ($6,000 for two people) on offer. Meanwhile, oenophiles with money to burn can win a dinner for six with Screaming Eagle winemakers at Meadowood Napa Valley, where guests can taste wines made by the acclaimed Cabernet producer paired with cuisine from Michelin-starred chef Christopher Kostow ($20,000).

“Those who come to Sotheby’s seeking the finest works of art, jewels, cars and wines are also interested in unattainable, extraordinary experiences,” David Goodman, an executive vice president at Sotheby’s, said in a statement. “IfOnly not only creates an opportunity to welcome new audiences to Sotheby’s, but provides our existing clients with access to unique events that amplify their interests and passions.”

What people choose to splash out on is changing, according to IfOnly CEO and founder Trevor Traina: Recent stats reveal that over 72 percent of people would rather spend their money on experiences than things. “It’s easy to see that the long-predicted ‘Experience Economy’ has arrived and continues to strengthen,” said Traina in a statement. “This investment enables us to realize the full potential of this trend, locally and across the globe.”
